To ALL wHoM 1T MAY ooNcERN:

, Be it knownthat I, WILLIAMl WEAVR, of Nashua, in the county ofHillsborough, and in the State of New Hampshire, haveinvented certainnew and* useful Improvements in Device for Smoothing and SecuringMarble; and I-'do hereby declare that the following is a full, clear,and exact description'tllereo', reference being had to the accompanyingdrawings, and to the letters of referencemarked thereon.

In the annexed drawings, making part of this specification, Areprescntsva metallic box, Awhich is provided with e movable bottom, B.Bolts C C, whose heads are countersunk so us to be Hush withl thesurface of the bottom B, pass through said bottom and through the top ofthe box, and are confined by means ofthe nut-s DD. These bolts and nutssecure the bottom B to the box A. e e represent small orices o`ropenings through the bottom B, connecting-.on the lower surface of thebottom with a'. series of radiating grooves, x z. d d represent u seriesof tapering grooves in the ends of the bottom B. The top of the box A isprovidedwithan opening, in whichsits the bottom of a tank', E,a ledgeupon said tank resting upon the'top of the box, around the mouth of theopening. The tank E has an opening'in its top, through'which it isirlled with water, and a small opening, a, in its bottom, through whichwater is allowed to escape. Thefbox A is filled with prepared sand, and

the tank E with water. The water escaping through the bottom of the tankE, carries the sand out through the openings e e in the bottomB of thebox, and the diverging angular channels x :cdistribute both the sand andwater on the surface of the stone or marble or slatethu't themachine maybe .working upon. One end of the box,A (as also the bottom B) is madewider than the other, because much of the marble and stone used ,is of atapering or Obelisk form, and the workman is enabled to apply the widerand heavier'end of this scourer tothe wide end ofthe Workthus workingmost where most'is needed.

Having thus fully described my invention, what.I claim as new, anddesire to secure by Letters Patent, isi- 1. The box A, provided with amovable bottom, constructed substantially as and for the purpose setforth, and of anysuitable material.

2. The use of a water-tank, E, incombinatiouwith the sand-box A,substantially as and for the purpose setA forth.

3. Contining the bottom B to the box by vmeans of bolts and nuts, saidnuts being constructed so as to answer as handles for the scourer,substantially asrepreseuted.

In testimony that I claim the foregoing I have hereuntosetv my hand andseal this 15th day of May, 1867.
